“…[Au III ], [27,28] X, [8,[27][28][29][30][31][32][33] [DCA], [15,17,18,20] [electrolyte] [34] , pH, [15,19,24] temperature [35,36] , initiation method [37] ) that enable to obtain, eventually in high quantity, AuNPs with radius ranging between 2 and 75 nm with narrow size and shape polydispersity. Among these parameters the reactant ratio, X, is the oldest and probably the most exploited to modify AuNPs size.…”

“…Attempts to tune the process by manually adjusting the pH value, though, produced no gold colloid at all, neither by thermal nor by ultrasonic initiation. [95,96] The extreme sensitivity of the reaction protocol to fine changes also becomes visible by the fact that nanoparticles with significantly smaller sizes are formed when the gold solution is added to the solution of sodium citrate. [97,98] Also, the addition of very small amounts of sodium chloride has a dramatic effect, [99] underlining the need for ultrapure water.…”

“…The colloidal particles formed in this way generally have small mean diameters and low polydispersities. Sonication may also be used to produce colloids [119,120]. Ultrasound treatment of an aqueous solution of H[AuCl 4 ] in the presence of glucose leads to ribbons of gold with widths of 30-50 nm and length of several micrometres.…”
